REFLECTOR: main gear brake lines

[Jack Sheehan]

I also ran the nylaflow inside a tube but terminated the nylaflow at the bottom
of the gear leg and used a braided line from there to the brake. Thought about
stuff hitting it on the runway and the heat from the brake. No 
problems 600 hours flying.
Oh Yeah!  The stuff on the runway never hits the gear it is always 
too busy going through
the MT prop.
